how much voltage should be there in earth neutral neutral line earth line in voltages

The Earth's Magnetism - A magnetic compass was used to help the sailors for navigational purpose. But recently it has been discovered that some migrant birds have magnetic sensors in their heads, which help to guide them using the Earth's magnetic field. William Gilbert suggeste..

When the N pole of the magnet points South and the magnet in the magnetic meridian. When the N pole of the magnet points North and the magnet in the magnetic meridian. At the two points marked X in figure, the earth's magnetic field and the magnet's field are exactly equal and opposite an..

Usually an electric appliance such as a heater, an iron, etc. are fitted with all the 3 wires namely live, neutral and earth. The earth wire is connected to the metallic body of the appliance. This is done to avoid accidental shock. Suppose due to some defect, th..

Let the object O be viewed with our eyes which is at a distance of r, making an angle q between the two eyes as shown in the diagram. The angle q , caused by the two lines drawn from the position of the two eyes to the object, is called angle of parallax. If we can consider OA a..

Domestic Electric Circuits - Electric power is usually generated at places which are far away from the places where it is consumed. At the generating station, the electric power is generated at 11,000 volts. This voltage alternates at a frequency of 50 Hz. The power is transmitted over lo..

The electric power line enters our house through three wires. One is called the earth wire or ground wire. This carries no electricity. The earth wire is connected to a large metal plate buried deep in the ground. The remaining two wires carry electricity. One of these..

Summary - Like magnetic poles repel and unlike magnetic poles attract. Soft iron gains and loses magnetism faster than steel. A magnetic field is a region in which a magnetic force may be detected. Magnetic field can be plotted with the help of a compass needle. A magnetic field line is a..

>The direction of the induced current is given by Fleming's right-hand rule. This forms the basis of the electric generator An electric generator is a device that converts mechanical energy into electrical energy In our houses we receive AC electric power of 220 V with a frequency of 50 Hz. There a..

Conclusion - There has been considerable development in our day to day life due to study and application of Conductors, Insulators, and Capacitors. Thunderstorms and lighting that flash, help us to maintain the potential difference between the earth and atmosphere. Electrostatic shielding..
